Scientists Identify New Organ

Scientists Identify New Organ

For Centuries, scientists, physicians, and scholars studied the human body, organs, systems, functionality, and so on. Every discovery paves the way for new findings, but since it’s 2017 most people firmly believed there’s nothing new to discover. Well, it turns out there’s a new organ you didn’t even know you have. How remarkable is that? Keep reading to find out more about this subject.

New Discovery

Prof J. Calvin Coffey and D. Peter O’Leary of the University of Limerick from Ireland have classified a new organ inside our bodies. In fact, the organ has been hiding in plain sight within the digestive system this whole time. The identification of the new organ only confirms the idea that there’s still a lot to discover as there’s substantial “uncharted” territory inside each person.

Even though at this point we know the name and structure of this organ, its functionality is still poorly understood. Studying it could improve* our health outcomes and create new ways to treat* abdominal and digestive diseases.

Findings, published in the Lancet Gastroenterology & Hepatology, identify the new organ within the digestive system as mesentery and for a long time, it was considered to be comprised of fragmented, separate structures. The latest research dismisses those claims and states that mesentery is a continuous organ.

Professor Coffey explains that the anatomic description of anatomy that had been used for more than 100 years is incorrect. The mesentery is quite complex and far from fragmented. Scientists from all around the world applauded the discovery and praised the incredible contribution to the field of medicine. In fact, the most well-known series of anatomy textbooks used by medical students worldwide, Gray’s Anatomy, has been updated to include the definition of the organ.

What is Mesentery?


The mesentery is a double fold of the lining of the abdominal cavity or peritoneum. It binds our intestine to the abdominal wall and ensures that everything is kept in place. Just because scientists classified it as an individual organ now, it doesn’t mean mesentery was unknown to scientists.

In fact, one of the earliest descriptions of the mesentery was written by none other than Leonardo da Vinci. However, for centuries the description was simply ignored and scientists considered it as a mere, insignificant attachment.

Back in 2012, Professor Coffey and a team of researchers carried out detailed microscopic examinations proving the mesentery is a continuous organ. Results of this particular research were published in the journal Colorectal Disease.

It’s important to bear in mind that identification of the new organ doesn’t rule out all past discoveries and the structure of our body. Instead, it is a reclassification that comes with a brand new field of science. This will yield positive effects for both patients suffering from digestive and abdominal diseases and doctors who’ll have more effective approaches to treatment.

Now, medical students, doctors, and scientists will investigate the role of the mesentery to improve* health outcomes in patients. What is known now is that you can’t live without the mesentery, which means the organ does play a certain role that has to be yet discovered. There are no reported cases of a human being living without mesentery.

DID YOU KNOW: mesentery is the 79th organ in a human body.

Hundreds of years ago, Leonardo da Vinci provided a detailed analysis of the human anatomy and described different organs including the mesentery. However, it was ignored as an unimportant attachment. It turns out, da Vinci was right as scientists from Ireland discovered that mesentery is, indeed, an organ whose full functionality is yet to be discovered.
